'Letters Patent No. 94,958', elated September 21, 1869.

TILELMACHINB.

The Scledule referred to in these Letters Patent making part of the same.

Mss-

To all whom it may concern to the 'letters of reference marked thereon, 'making part of this specification.l

, Thisiiivention relatestoarrangement of the several `parts 'of which the machine is composed, combined withthe construction andarrangementof' the devicesu for` y andmanner of operating the -followers and'cut-oii",

' and has for its object to simplify and cheapen the construction, and to shorten the stroke of the followers,

andthereby lessen the .power required to operate them.

Figure 1 is a vertical transverse" section of a tilemachine constructed and arranged according to my im- `r provement.

Y vh "i'gure 2 is a horizontal section of the same, taken just below the top of the frame, containingthe moulding-chambers, followers, and cut-off. r

Similar letters of reference indicate corresponding parts in the several figures.,

A repr'esents the frame of the machine, made of suitable material and dimensions, in which are ar- I ranged the moulding-chambers F, followers B, andcut C is the clay-hopper, arranged over the frame A, in thebottom of which are suitable openings M, for the issue of the clay direotlyfinto the moulding-chambers F ing-chambers, one in each'end of the frame, and is consequently provided with two followers or plungers B,

'for'.forcing the mud through the dies G, and a double` The followers B are connected together by four longi- The ends of the toggle-hars are hollowed out, to receive thecrank at one"I end, and the semicircular belarings I, on the inside ofthe followers, at the other end.

The simplicity and other advantages of this arrangement will be apparent, as it saves much labor and cost'of fitting up, the only parts requiring to be made smooth and well finished being the crank and the ends of the` toggle-hars bearing against itY The cut-olf K is urade double, to correspond with .the issues M, and is furnished with downward-projecting catches, N, and is actuated by the projecting point of Vthe cam L, on shaftD, which engages with the downwarfdv'projeoting .catches as--theshaft is revolved.`

The cam L and the downward-projecting catches N ,of the cut-oli' are arranged with reference to eac-h other,

so as to effect the movement of the cut-off in' opposite direction to the movement of the follower, and cause them to meet the latter about in the centre ofthe issues, thus shortening the movement required of the followers, as they are effective in forcing the clay through the die as soon as the issuesM are closed by the out-off.

As usually constructed and applied, the feed-arm P presses the clay down upon the bottom of the hopper C over its entire surface, causing great friction and strain upon the machine, and consequent'loss of power.I

In order to obviate this, I have devised the feed-arm P, (a top view of which is shown detached in Figure 3,) of such form as to drive .the -clay outward from the centre to the issues M,Ithc'end of the arm being formed with the usual inclined surface adapted to press the clay down through them.

I make no claim to' thel several parts of which this -machine is.'composed, in themselves considered, as

they have vbeen used for similar purposes; but

What I claim as new, and desire to secure by Letters Patent, is-

The reciprocating plnngersB B, connected by bars X, and operated by crank J and toggle-hars H, turning upon semicircnlar bearings I, in combination with v.double cut-off K K and cam L, when said parts are constructed and arranged to operate with relation to each other, as and for the purpose herein set forth.
